Coomassie® Brilliant Blue R-250

G-Biosciences' Coomassie Brilliant Blue (CBB) G-250 and R-250 Stain are based on a colloidal Coomassie stain. CBB G-250 and R-250 stain proteins with high band visibility. The staining of gels with CBB G-250 and R-250 allows the examination of protein bands even during the staining process.


After the staining process, the band intensity may be further enhanced by de-staining the stained gel in our CBB De-Staining Solution or 30% Methanol. CBB G-250 and R-250 Stains have a sensitivity of staining 8-10ng protein/band (e.g., 8-10ng of BSA is visible in 4-20% SDS acrylamide gels). The supplied volume is suitable for 40-50 mini gels (8 x 10cm) & 20-25 large gels (12 x 15cm).


G-Biosciences' Coomassie Brilliant Blue R-250 and G-250 are both offered in dry powder form and convenient ready-to-use solutions.
A destaining solution is also offered.
